Balzan of the Cat People #2: The Caves of Madness by Wallace Moore
Pyramid Books, 1975
Price I paid: 1¢ ($4.00 with shipping and handling)

Human castaway on a planet light years from earth,

Balzan had known many unearthly creatures in his alien home. The cat people had raised him and given him feline knowledge; the winged Aeri had adopted him; beautiful Ryla had loved him in spite of his naked, wingless shoulders.

Now Balzan was being held captive by another tribe of winged humanoids, living deep in underground caverns lighted only by glowing fungi. In this strange world where all women were the wives of all men, where no one was owner or owned, Balzan was plunged into terrifying adventure…with the slimy, gigantic night crawlers…with the most horrible monster of all, the fiendish Sl’yth!

Space flight Ares Probe One was thirteen months away from earth on a manned journey to Mars.

Then IT happened!

The craft was plucked out of the solar system to crash on a wild planet never seen by man. Only an infant boy, sleeping in stasis inside a safety cube, survived. He was to become Balzan, adopted son of a tribe of bipeds resembling earth cats!

THE BLOOD STONES

Reptilian raiders, flashing deadly neutron swords, had taken Balzan’s cat-people into slavery to satisfy the blood-lust of an insatiable queen. Only Balzan could hope to rescue them. But first he must learn the terrible truth about the evil blood stones, even if the knowledge destroyed him!
